Debian: Security update for libmodplug

Several vulnerabilities that can lead to the execution of arbitrary code have been discovered in libmodplug, a library for mod music based on ModPlug. epiphant discovered that the abc file parser is vulnerable to several stack-based buffer overflows that potentially lead to the execution of arbitrary code. Hossein Lotfi discovered that the CSoundFile::ReadWav function is vulnerable to an integer overflow which leads to a heap-based buffer overflow. An attacker can exploit this flaw to potentially execute arbitrary code by tricking a victim into opening crafted WAV files.

Hossein Lotfi discovered that the CSoundFile::ReadS3M function is vulnerable to a stack-based buffer overflow. An attacker can exploit this flaw to potentially execute arbitrary code by tricking a victim into opening crafted S3M files. Hossein Lotfi discovered that the CSoundFile::ReadAMS function suffers from an off-by-one vulnerability that leads to memory corruption. An attacker can exploit this flaw to potentially execute arbitrary code by tricking a victim into opening crafted AMS files. It was discovered that the CSoundFile::ReadDSM function suffers from an off-by-one vulnerability that leads to memory corruption. An attacker can exploit this flaw to potentially execute arbitrary code by tricking a victim into opening crafted DSM files.

It was discovered that the CSoundFile::ReadAMS2 function suffers from an off-by-one vulnerability that leads to memory corruption. An attacker can exploit this flaw to potentially execute arbitrary code by tricking a victim into opening crafted AMS files.

Updated packages are available from security.debian.org.

Several vulnerabilities that can lead to the execution of arbitrary code
have been discovered in libmodplug, a library for mod music based on
ModPlug.  The Common Vulnerabilities and Exposures project identifies
the following issues:

CVE-2011-1761

   epiphant discovered that the abc file parser is vulnerable to several
   stack-based buffer overflows that potentially lead to the execution
   of arbitrary code.

CVE-2011-2911

   Hossein Lotfi of Secunia discovered that the CSoundFile::ReadWav
   function is vulnerable to an integer overflow which leads to a
   heap-based buffer overflow.  An attacker can exploit this flaw to
   potentially execute arbitrary code by tricking a victim into opening
   crafted WAV files.

CVE-2011-2912

   Hossein Lotfi of Secunia discovered that the CSoundFile::ReadS3M
   function is vulnerable to a stack-based buffer overflow.  An attacker
   can exploit this flaw to potentially execute arbitrary code by
   tricking a victim into opening crafted S3M files.

CVE-2011-2913

   Hossein Lotfi of Secunia discovered that the CSoundFile::ReadAMS
   function suffers from an off-by-one vulnerability that leads to 
   memory corruption.  An attacker can exploit this flaw to potentially
   execute arbitrary code by tricking a victim into opening crafted AMS
   files.

CVE-2011-2914

   It was discovered that the CSoundFile::ReadDSM function suffers
   from an off-by-one vulnerability that leads to memory corruption.
   An attacker can exploit this flaw to potentially execute arbitrary
   code by tricking a victim into opening crafted DSM files.

CVE-2011-2915

   It was discovered that the CSoundFile::ReadAMS2 function suffers
   from an off-by-one vulnerability that leads to memory corruption.
   An attacker can exploit this flaw to potentially execute arbitrary
   code by tricking a victim into opening crafted AMS files.


For the stable distribution (squeeze), this problem has been fixed in
version 1:0.8.8.1-1+squeeze2.

For the testing (wheezy) and unstable (sid) distributions, this problem
has been fixed in version 1:0.8.8.4-1.

We recommend that you upgrade your libmodplug packages.
